To all whom it may concern:

Be it known that I, MICHAEL H. MALO EY, of Plymouth, in the county of Plymouth and State of Massachusetts, a citizen of the United States, have invented a new and useful Im rovement in S innin Mechanisms, b

of which the following is a full, clear, and

exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

My invention relates to an improvement in spinning mechanisms or devices which have as elements of their construction a r0- tary traveler ring or other rotating part, a base on which the traveler ring or other rotating partis mounted to rotate and a holder connecting with the ring and extending inside the base to cooperate therewith whereby the ring may be retained to properly rotate.

My invention relates also to an improvement in the relative form, adaptation and arrangement of the various parts of the device. 1 v v v It is among the essential objects of my invention to so inclose the working parts or bearings of the device as to prevent the entry of lint or other foreign matter to them;

to so adapt and arrange the working parts or bearings that lint or other foreign substance cannot easily collect or lodge upon them, and to so adapt and arrange these parts or bearings, also, that should lintor other substance enter the interior working parts or bearings such substance, will be swept away or dislodged and directed out of such parts.

It is a further object'of my invention to provide a construction in which the traveler ring will be retained to rotate with as nearly absolute precision as possible consistent with a free and proper retention of the ring, also, to provide a construction in which the traveler ring will be retained to have at all times proper freedom of rotation with respect to the traveler though tending to prevent an excessive freedom of rotation of the traveler speed as it might do especially when im-- polled by the pulls of strong yarn on the .top bearing surface of the base.

traveler. In other words, I have found that the advantages to be derived fro-m a rotary ring are materially increased if the mountstood by reference to the drawings, in

Fig. 17 is aplan of a further type of base embodying my invention, the base being looked at from the top side thereof; Fig. 18

ring is shown mounted directly upon the base though in so 'far as my invention is concernedian auxlhary rotary ring or other rotating part 4 may be, as it preferably is, as shown in Fig. 2, interposed between the 7 traveler ring and base.

5 is the holder which cooperates with or engages the base-an'd by means o'f which -the traveler-ring is retained to properly rotate.

The base '1 is attahab'le'to -a ring rail or other fixture of support (not shown). F or the purpose of this attachment the base is provided witha seating plates which is secured to the ring rail in an ysuitable man- 116i. ing init. Trom the point of or around this 'l-he'seating 'plate '6 has a central openope'nin g'the base is extended upwardly bya body portion 7. This body portion of the base is in the nature of'a'n ii'nperforate casing preferably annular form. At the 7 point of its top edgethe body of'the'base is extended inwardly for some little 'dist'ance by 'a flangeforming portion 8. This-flanged portion of thebaseacts to provide not only a bearing surface for supporting the traveler ring or auxiliary ring interposed between the-traveler ring and base, as above described, but acts also to assist in the reten- =tion of the'holder as will hereinafter b'e'ex- 'plained.

Referring now anore particularly to the bearings or bearing surfaces presented by the "base, attention is first dire'cted to the surface orbearin 'g 9 presented by the'inside of thebody portion of the base. This'sur'face or hearing will for purposes of expediency be "termed an inner radial bearing inasmuch as it acts, as will *hereinafter be explained, by "the bearing of the holde'r against it to restrain the movement of the holder and traveler ring secured to it as against radia'l displacement. In the embodiment of my invention shown in "Figs. 1 to 8, inclusive, the bearing'surfacei9 iss-continuous surface or :bearing and preferably of some considerable depth extending preferably in parallel a-linernent with "the vertical axis of the traveler ring'assuming this 'ring to be 10- catedand normally operating in "a horizontalplane. It is also to be observed that this surface orbearing 9 is considerably removed :from the jpoin't of the vertical axis -of-the traveler ring. The base presents also a further continuous bearing surface .10 which surface or bearing is presented by the under side of the flanged portion 8 of the base. This surface or'bearin'g will for purposes of expediency be termed an inner axial surface or bearing inasmuch as it acts to retain the holder and traveler ring as against displacement in an axial direction during the operation o'f the traveler ring. The bearing surface 10 is preferably a narrow bearing surface and extends also preferably at right angles to the said axis o-f the traveler ring. Thebase presentsalso what maybetermed a top surface or bearing 1 1, the samebeing presented by the top side or face of the flanged portion 8 thereof. This surface or bearing in-thepresent embodiment of my invention is -a continuous surface or bearing likethesurface or hearing 10 and jpreferably extends also at right angles "to the axis of the ring. It is upon this surface or bearing 1-1 that the tra'X' eler ring, or other rotating part interposed between the traveler ring and base, rests to rotate.

The traveler ring 2 may he of any suitable construction. In practice I prefer 'to -employ and'adapt the construction and relation of the parts to the ordinary twoflanged ring in order that old rings may be used if desired.

The auxiliaryring or washer t'intcrposed as shown between the traveler ring andbase is a relatively thin fiat ring annular in form and is made usually of metal or fiber dependent upon the circumstances under which it is used. It is, as will hereinafter be explained, attached to the traveler ring and rests upon the top bearing surface of the base to rotate thereon. In this construc- ''tion it is to beobserved that this auxiliary ring is ofsuch size that it may cover the entire top bearing surface of the base and 5 extend inw'ardly for some little distance beyond the inner edge of the flange 8 of the base on 'Whieh the ring rests. The ring is also of sufficient size to extend outwardlybe- 'yond thebase on which it restsand this outwardly-extending portion of the ring is preferablyturned down to form an annular 'turned edge'or rim 13.

The holder 5 connects 'with the traveler ring and from the point of its connection therewith extendsdownwardlv in'to'the base to -coiiperatewith the axial and radial bearlngs of the base be'fore mentioned. In form the holder is annular and comprises a clamp-- ability'of this part'of the holder is such that when "the auxiliary ring or washer "l is employed this auxiliary rmg may be bound 'to the traveler ring by the same clamp that binds the holder to the traveler ring so that the auxiliary ring will rotate with the trav eler ring. In other words, the adaptation of the auxiliary ring in relation to the holder and traveler ring is such that from the point of its engagement with the traveler ring it may extend downwardly and around the inside bottom edge of the auxiliary ring by which these parts become bound together. From the point of its attachment as aforesaid the holder isabruptly extended downwardly by a neck portion 15 which extends through the opening framed by the flange portion 8 of the base into the interior of the base to a point just below the axial bearing surface 10 thereof. From this point .the holder extends outwardly to cooperate with the base by ashoulder 16 beneath the axial bearing surface 10thereof and thence downwardly by a body portion 17 alongside the radial bearing surface 9 of the'base. The

downwardly-extending neck portion 15 of the holderrit will be observed is, some little distance removed from the inside edge of the flange 8 of the base on which account a vertical inside opening 18 is formed at a point just adjacent to the joint betweenthe bearing surface of the base and the ring resting upon it. The holder in its shoulder portion 16 and body portion 17 is formed to present separate bearings, at the points of engagement between these parts and the adjacent bearing portions of the base with vertical openings or clearances between these bearings In other. words, the holder is formed or bent whereby the shoulder portion 16 of the holder will present separate outer axial bearings 19 inasmuch as they are adapted to engage the inner axial bearing surface 10 of the base, while the body of the holder on the outside presents separate outer radial bearings 20, inasmuch as they are adapted to engage the inner radial bearing surface 9 of the base. Between these separate bearings of the holder are formed vertical openings or clearances 21. These openings are preferably of some considerable depth and extend from the opening 18 with which they connect downwardly to a point outside the joint betweenthe body of the holder and the base. e 1

In Figs. 9 to 18, inclusive, I have shown a further-embodiment of my invention in the fact that the openings between the shoulder and body portions of the holder and ad jacent portions of the base, which openings connect with the opening 18 before men tioned, are formed not in the shoulder but in the base, the base 1 in other words, being like the base 1, but" formed to present a series of separate inside axial and radial bearings with openings or clearances between these bearings, while the holder 5 is like the holder 5, but formed to present at the points of itsshoulder and body portions outer continuous axial and radial bearing surfaces which cooperate with or engage the respective bearings of the base. rateaxial bearings of the base are designated 22. Theopenings or clearances between these bearings are designated 23. The separate radial bearings of the base are designated 24. The openings between these hearings are designated 25. The continuous axial bearing surface of the holder is designated 26, thecontinuous radial bearing surface 27. The disposition and arrangement of the respective inner axial bearings 22 of the base are such that the openings 28 be tween these bearings will connect at their inner ends with-the opening 18 before men tioned and at their outer ends with the openings 25 between the radial bearings of the base. openings and extend from the point of their connection with the openings 23 between the axial bearings 24 as aforesaid to a point outside the joint between the body of the base and holder.

In Figs. 14 to 16, inclusive, I have shown a further embodiment of my invention which is preferably like the construction shown in Figs. 9 to 13, inclusive, just referred to, except that the openings 23 be 1 tween the axial bearings of the base 1 on the under side of the flange-forming portion 8 of this base are in the base 1 shown in these figures extended upwardly through the flange 8 on which account the top bearing surface 11 of the base 1 of the flanged portion 8 thereof will present not a continuous top bearing surface as in the construction previously described but a surface consisting of separate bearings with openings between these bearings, which openings are vertical openings, as it were, and connect immediately with the openings formed at the point of the joint between the axial and radial bearing portions of the base and holder. In connection with this modified construction attention is directed to the fact thattheopenings through the flange portion of the base are preferably arranged to leave a continuous bearing rimor edge 28 on the outside against which the ring 1 resting upon the base, is adapted to bear, on which ries of separate top bearings 29 on which the ring rests with horizontal openings 30 between these bearings. The openings 30 connect with the vertical opening 18 formed by foreshortening the flanged portion 8 of These openings 25 are vertical 1 The sepathe base with respectto the neck portionof the holder 5*. In other respects the base issubstantially like the base 1 being provided-with separate inside axial and radial bearings 22, 2 1, respectively, with-connected openings 28, 25, respectively, .ibetween'these bearings. In this connection it will beobserved that the openings 23 and within the base 1 (which openings connect with the opening 18), are formed at the point of and beneath the raised bearings 29.

Other modifications might be shown, but the above illustrate the preferred embodiments of the different phases of my invention. It.:may also be explained and especiallyawith reference to the base and holder that a base or holder entailing any of the above constructions may be struck from blanks, which'is the way I prefer to make them.

In referring to the special utility-of the elements of the above described construe tion attention is first directed to the fact that either of the bases 1, 1 1 or 1 forms, as it were, a casing inclosing the interior working parts or bearings located within the base and practically sealing them from the ingress of lintor other foreign matter.

Moreover, foreign matter'cannot wellenter 'these-working parts or bearings from inside the base inasmuch as they are covered and protected by the holder. Practically the only part at which dirt or lint might enter is at :the point wherethe ring or other rotating part rests to rotate upon the top bearing surface of the base, the lint entering from the outside. In a construction like that shown in Figs. 1 to 16, inclusive, the ring rests-upon the base in such manner that lint cannot easily enter at this point owing to the fact "that the ring maintains a continuous bearing contact with the base at the point of entry. 'In the event of lint or dirt .entering the bearings or working parts their adaptation and arrangement aresuch that the lint will be swept away and directed out of the bearings.

In that embodiment of my invention shown in Figs. 1 to 8, inclusive, assuming dirt or lint to enter from the outside at the point of the joint between the top bearing surface of the base and the part rotating upon it. Owing to the wiping action of the rotating part over thissurface the tendency will be to outwardly expel such matter from this joint. Should lint continue to work farther into the joint the tendency will be for it to eventually enter the opening 18 left between the inner edge of *the flange 8 and the neck 15 of the holder and thence work out of the interior parts by falling downwardly through this opening and through the openings 21 in the holder with which the opening 18 connects.

1 In that embodiment of my invention shown :in Figs. :9 to 20, inclusive, where separate openings :are shown not in the holder but in 'the base, any lint itllat might enter the opening 18 by way of the joint between the top bearing surface of @the base and the part rotating upon it will work out ofzthis opening through the respective openings 23 and 25 ill). the base to a pointoutside the joint between 'tllGEllOldGl and thebase. I prefer, however, the construction first described where the openings-are formed \in the holder inasmuolrasthe connected openings are more direct and the vibratoryzaction of the holder during its operation assists in expelling dirt or lint by way of the openings between its separate bearings.

The provision of separate lbearings and interposed openings at the points of the joints between the working parts=tends also to .free these joints of foreign matter that might enter them inasmuch as the tendency of the rotating part is to impel dust or lint to a *point where it will enter the openings and-becomeexpelled from'the joints. Such advantage resides in all the types of construction shown at the points of the joints formed between the base and holder. It resides also atthe point of the joint between 'the top :bearing surface of the base and the rotary .part resting upon it asshown in Figs. 1a to .20, inclusive, where the top flanged portion'of the base presents separate hearing surfaces with openings between them. In other words, lint that might enter the joint at this point will in the operation of the rotating :part be swept off the separate bearings to fall through the openings between these bearlngs and thence out from between the bearing surfaces of the base and holder by way of the openings arranged at the point'of the oint between these parts.

In Figs. 1-7 to 20, inclusive, the utility of the construction resides further in the fact that not only does the top bearing surface of the base present a series of separate raised bearings 29 oif which dust or lint may be swept by the rotating part resting thereon into the openings 30 between these bearings, but the extension of the openings is such that air may enter from the outside at the points'of these openings, thence pass to the vertical opening 18 between the foreshortened end of the flange 8 of the base and the neck portion 15 of the holder from whence it may circulateor pass out through the openings 23, '25, formed between the bearing surfaces of the base and holder to a point outside the joint formed by these bearing surfaces. In other words, not only may dust and lint be expelled through these connected openings, but'the construction provides means whereby a circulation of air may be introduced to pass through these separate openings and assist in such expulsion. By providing in the respective bearing surfaces separate bearings further utility rea sides in the reduction of friction between the bearing parts. This is of considerable importance inasmuch as a large amount of friction-resisting surface is apt to interfere with the free and proper operation of the traveler ring. In this connection it will be exp ained that as long as the friction-bearing surfaces remain free of foreign matter which would interfere with the proper operation of the traveler, a relatively large amount of friction-bearing surface might not essentially interfere with the proper operation of the traveling ring for in this con nection it will be explained that while it is necessary that the traveler. ring have a free and proper rotary movement yet it is equally essential for its proper operation that it be restrained from rotating at excessive speed or so as to gather. momentum when impelled by the'pulls of the yarn upon the traveler. In such case when the frame is stopped the ring will continue to rotate with the result that the, yarn is apt to be broken or if twisted strands of yarn are being spun the yarn will snarl. The difliculty with the continuous bearings between the working parts is that after much use they are apt to become clogged with dirt or lint which impedes even if it does not stop the action of the traveler ring as it might in some cases. By providing the friction-bearing surfaces with separate-bearings and providing for the eliminationof foreign. matter between these bearing surfaces the difficulty abov pointed out is overcome while provision is made for retarding the rotary action of the traveler ring and preventing excessive movement thereof by the particular arrangement and disposition of the operating parts which brings in the element of leverage to prevent the pull of the yarn upon the traveler from impelling the ring at too high a speed. In

this connection attention is directed, as was before pointed out, to the fact that the interior bearings or bearing surfaces of the base and especially the radial bearing surface thereof against which the holder is adapted tobear for preventing radial displacement of the traveler ring, is considerably removed from the axial'center of this ring. Such removal arises primarily from the manner in which the holder cooperates with or engages the base to provide these bearings, the holder being, as before described, extended outwardly to form a shoulder engaging the axial bearing of the base and thence downwardly by a body portion to engage the radial bearing thereof.-

By reason of such removal of the bearings from the axial center'of the traveler'ring a greater force is required to overcome the resistance of the frictional resisting surfaces between the base. and. holder than if these surfaces were nearer thev axial center of the ring. The reason for this is a matter ofleverage, for assuming power to'be applied to the traveler ring, the farther the work or resistance is away from the axial center of this ring the greater must be the force to overcome the work or resistance. The immediate advantage of such removal of the bearings resides'in the fact that the traveler ring and holder influenced by such resisting surfaces resist the rotary impulsion of the traveler: as it is rotarily impelled by the yarn with the effect that the traveler ring and holder normally rotate at a lesser speed than that of the traveler, or in other words, at such speed that the traveler ring will not gather momentum during its operation. Moreover, by controlling the holder and traveler ring to'resist the rotary impulsion of the traveler as aforesaid, the normal resistance of these parts to the traveler is a more constantfactor than if a large amount of frictionally contacting surface were relied upon to effect such resistance.

By graduating the amount of frictionally contacting surface between the working parts and the base as may be done by providing separate bearings as aforesaid and by graduating the size of these bearings and also the relative distance these bearings are from the axial center of the traveler ring' just the proper amount of resistance may be imparted to the holder and traveler ring to resist the rotary impulsion of the traveler dependent upon the work to be done. When light yarns are being spun which impart but little pull tothe traveler to rotarily impel the traveler ring, then the amount of. frictional resisting surface between the working parts and base need not be such as will materially influence the speed of the traveler ring. When, however, heavier yarns are being spun then of course the frictional resistance between the working parts must be increased in orderv to insure a proper operation of the'holder. and traveler ring. Usually it is desirable to make the auxiliary ring interposed between the traveler ring and base of some material having an increased frictional resistance over metal, as for example, fiber, leather or similar material. By making the auxiliary ring of fiber or leather I have found that its increased frictional, resistance with the top bearing surface of the base acts: to a marked degree in graduating or controlling the speed of the traveler ring and holder especially dur ing the spinning of heavy yarns. As I have already explained, I prefer to use anauxiliary ring 4: between the traveler ring and base under lall'circ umstances even though this ring he made ofmetal for a wearing surface is provided in such a ringand as the auxiliary ring is a relatively thin flat which especially fits it fora bearing ring as compared with the traveler ring WlllCll oftentimes; owing to imperfections or wear, especially if the traveler ring be an old one, unfit's it for becoming a truebearing ring.

In: connection with the auxiliary ring attention is called to the down-turned edge or rim L3. This rim: or edge actsas a means for: reinforcing or strengthening the auxiliary ring: It acts also to prevent'vibra-tion. It assists,-also, by its overlapping the base at the point of the joint between the auxiliary ring and the top bearing surface of the base; inpreventing dust or lint from entering this joint from the outside.

By the term rotary traveler'ring and r otary holder therefor as referred to herein and thecl'aimsis meant a rotary traveler ring and bolder haying either an entire or'partia-l rotation inasmuch as the construction herein" described is applicable to a rotary traveler ring and bolder having a partial rotation; 1 I
